Trying to figure out if a thread is visible to guests...

[BirdOPrey5]

I opened showthread.php and found this code which deals with if the user has permission to view the thread:

PHP Code:

// *********************************************************************************
// check forum permissions
$forumperms = fetch_permissions($thread['forumid']);
if (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']))
{
    print_no_permission();
} 


The fetch_permissions function can take an optional second parameter to fetch permission for another user...

So I have this in a plugin:

PHP Code:

    $bopguest = 0;

    $bopguest = fetch_userinfo($bopguest);

$forumperms = fetch_permissions($threadinfo['forumid'], $bopguest);
if (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']))
{
    $joetest = "NO PERMISSION";
}
else
{
    $joetest = "ok";
} 


if $bopguest equals any true userid it works as expected... however to get guest/not-logged-in permission I thought maybe I could set $bopguest = 0. But that doesn't work I always get no permission even when guests do have permission... and yes $threadinfo['forumid'] is valid on the hook I am using.

Any ideas? I don't see any special code to deal with guests only...
